Discussion

Analysis reveals higher NO2 levels in homes using natural gas compared to biogas, highlighting indoor air quality concerns.

Mean kitchen NO2 concentrations were significantly higher when using natural gas compared to biogas, indicating health risks.
Natural gas increased NO2 exposure by 2.8 ppb, or about 60%, demonstrating severe air quality implications.
Analysis utilized linear mixed-effect regression models to quantify the relationship between fuel type and indoor air pollutants.
Findings suggest evaluating alternative fuels' health impacts in residential cooking is essential for public safety.

Benka-Coker et al. (2025) studied this question.
